Definitions
- the present invention falls within the technical sector of solid waste treatment processes, specifically in relation to biological treatments of organic solid waste by aerobic (composting) or anaerobic (anaerobic digestion) techniques.
- the speed limiting stage is methanogenesis from volatile fatty acids generated during hydrolysis.
- the slowest stage is the hydrolysis of the particulate material and the solubilization of the organic matter in the liquid medium.
- the organic fraction is obtained after a series of previous processing steps and finally separated through a thrommel (with a passing light between 30 and 90 mm). Consequently, FORSU is in particulate form and the hydrolysis and solubilization of organic matter can be significantly increased by using the indicated pretreatments.
- the present invention focuses on the application of biological pretreatments on FORSU.
- several studies are carried out for the pretreatment of lignocellulosic residues, with the use and inoculation of specific enzymes capable of hydrolyzing this type of material.
- the main operating variables in biological pretreatments are usually the type of inoculum used as an enzymatic agent, the percentage of inoculation and the contact time between the residue and the inoculum.
- the invention consists of an operative process through which, by means of the application of a biological pretreatment consisting of the mixture of a solid organic residue (for example, the FORSU or other organic solid residue of similar physicochemical characteristics) with compost as an enzymatic agent , it is possible to accelerate the speed of hydrolysis and increase the anaerobic biodegradability of the residue subjected to pretreatment, since it is considered that the hydrolytic stage of a soluble particulate substrate is the limiting step of the overall speed of the anaerobic digestion process.
- the operative procedure consists in mixing, by stirring, the solid organic residue, which will be subsequently biomethanized by anaerobic digestion, with mature compost for 24 hours at atmospheric pressure and room temperature.
- the compost used as an additional biological agent is generated in the same procedure and its addition is carried out by means of a recirculation of the product resulting from aerobic composting to the mixing unit prior to anaerobic digesters.
- the percentage of inoculation with compost must be between 2.5% and 5% by volume.
- Figure 1 Represents a conventional flow diagram for the treatment, at the industrial level, of the FORSU, also incorporating a compost recirculation line for performing the pretreatment detailed in the present invention. Listed below are each of the elements that make up the process:
- Residue A Residue that is intended to be biomethanized by anaerobic digestion, for example FORSU.
- Waste B Waste that acts as a source of microorganisms for the development of anaerobic digestion, for example anaerobic sludge from an Urban Wastewater Treatment Plant that has anaerobic digesters in its facilities. 3. Waste mixing unit.

Abstract
L'invention concerne un procédé fonctionnel par le biais duquel, par application d'un prétraitement biologique consistant en un mélange de compost mûr, avec la fraction organique des résidus solides urbains, ou d'autres résidus solides à caractéristiques physicochimiques similaires, on parvient à accélérer la vitesse de l'hydrolyse et à augmenter la biodégradabilité anaérobie du résidu, étant donné que la dégradation d'un substrat de particule soluble est l'étape cinétiquement limitante dans la digestion anaérobie.
